Guanyu Qian is originally from Beijing, China. He received his Bachelor's degree in Applied Physics and Economics from the University of California, Davis, in 2022. During his undergraduate studies, he conducted research and experiments in particle physics, including background radiation detection and muon lifetime measurement.
Currently, he is a Ph.D. student working with Prof. Xiaofan Cui on the design and control of point-of-load voltage regulator modules (VRMs) for next-generation AI datacenters.
Applying reinforcement learning to point-of-load (PoL) converter control — learning a hybrid large-signal / small-signal policy that delivers fast transient response while staying provably stable across the full operating range.
Design and modeling of multiphase trans-inductor voltage regulator (TLVR) and uncoupled PoL topologies for high-current, fast-transient power delivery — analyzing transient performance, current sharing, and small-signal behavior.
A high-power, interleaved multiphase boost converter for electric-vehicle traction battery systems — pushing power density and efficiency with wide-bandgap (GaN/SiC) devices and robust multiphase control.
“We power AI and scale computing.”

Part-time volunteer who drops in to help and hand out solutions. His method is unconventional: he sketches doodles and crafts totems to summon spirits for each circuit, then dances through the rituals, praying they'll converge. Improbably — they do. Now an analog designer at OmniVision.
Previously worked with me on CMCD wireless power transfer.

A collaborator from UCLA CHIPS (Prof. Subramanian S. Iyer's group). Together we explored the integration of 48 V-to-1 V vertical power delivery for point-of-load conversion — the topic of Ben's master's thesis, recognized with an Outstanding Thesis Award. He is now with IBM.
Four professors had a lasting impact on my undergraduate experience and permanently changed the way I view research, engineering, and teaching.
In the spring of 2022, a three-month, research-like experience in PHY 122B with Prof. J. Anthony Tyson taught me a lesson that shaped my research attitude and gave me lasting motivation to continue pursuing research.
In the fall of 2020 and spring of 2021, I took two upper-division ECE courses with Prof. Weijian Yang. His teaching shaped the way I approach engineering problems. One quote from him still stays with me today.
Throughout 2021, I took a year-long course series with Prof. Dong Yu, which laid a solid foundation for my understanding of electromagnetics. That foundation still plays an important role in my current research.
In the fall of 2020, I took classical mechanics with Prof. Richard T. Scalettar. His passion and enthusiasm for passing knowledge to students deeply shaped the way I think about teaching. His influence helped me understand that teaching is not only about explaining material, but also about inspiring others.
Today, I strive to pass this influence forward through teaching, discussions, and research. Having taught more than 500 students, I hope to continue sharing the same kind of motivation, curiosity, and care that these professors once gave to me.
